RESULTS OF MAZE PROCEDURE FOR TREATMENT OF ATRIAL FIBRILLATION USING RADIOFRIQUENCY ABLATION IN PATIENTS UNDERGOING MITRAL VALVE REPAIR OR BIOLOGICAL MITRAL VALVE REPLACEMENT
Main Article Content
Abstract
Objective: Evaluate the outcomes atrial fibrillation treatment with Maze procedure using radiofrequency ablation in patients undergoing mitral valve repair (MVR) or biological mitral valve replacement (BMVR). Subjects and methods: We described a series of cases. Results: There were 95 patients, mean of age was 62.3 ± 8.3 years. Men accounted for 52.6%. Palpitation was presented in 44.2% of cases. Maze procedure was performed in all patients. The in-hospital mortality rate was 1.1%, 14.7% of patients suffered from early complications. The average follow-up time was 24.3 ± 14.2 months. At the endpoint of follow-up, there were 3 patients who died and 5 patients who had permanent pacemakers implantation. The rate of freedom from AF at first month, 3rd month, 6th month, 12th month and the end of the study was 82.9%, 73.4%, 76.6%, 84.8%, 82.9% and 72.6%, respectively. Conclusion: Maze procedure using radiofrequency ablation in patients undergoing MVR or BMVR was safe and effective with a high rate of sinus rthythm restoration.
